Application filed-August 14, 1925. Serial No: 50,226.

This invention relates to improvements in safety razors and particularly of the class in which a blade is detachably held between complemental members of a blade holder that is movably su ported in the razor frame for retaining the lads in shaving relation to a guard.

The object of this invention is to provide means for releasably retaining complemental blade holder members with a blade therebetween, with means associated with. said retainin means and with the razor frame for retaining a blade ed e in shaving relation to the guard, which a so embodies means for adjusting the proximity of the bladeedge to the guard and so retaining the blade'for shaving to provide for obtaining so-called close or coarse shaves.

The invention com rises novel details of improvement that wil be more fully hereinafter set forth and then pointed out in the claims.

teeth 5 over or against which the bla e 6 is to be located for shaving. The blade holder comprises complemental members 7, 8 adapted to lie against the blade to retain the latter flatwise respecting the guard, as well as for stropping, said members being movable relative one to another to admit and release the blade. The member 7 is secured to a shaft 9, as bymmeans of curled portions 7 of said mem r receiving the shaft which portions may be secured to the shaft by indenting the metal of said portions into depressions of the shaft, as indicated at 10, (Fig. 10), or in any other desired way.- The member 8 is shown provided with a curled portion 8' journaled upon shaft 9 so that the member 8 may swing relatively to the member 7 (Figs. 6 and 12) The shaft 9 is journaled upon and between the uprights 2 and 3, whereby the blade holder members 7, 8 may be swung or rocked relatively to the guard. The blade holder member 7 is shown provided with spaced projections 11, (Fig. 12), on the side opposing member 8 adapted to receive notches or recesses 6 near the heel of the blade, at the ends of the same, for locating the blade upon member 7 and retainin the blade from shifting thereon, so the b ade edge will be in proper shaving position res ting the guard when the parts are assem led for shaving. The projections 11 are preferably of greater len h than the thickness of the blade so as to pro ect into recesses or openings 8 in holder member 8, (Fig. 12 when the latter is folded upon the bio. e. The member 8 is detachablglretained upon the blade by means i of a slide e retainer 12 shown substantially in the form of a bar located along the surface of the member 7 opposite its blade receiving surface or side, (Figs. 8 and 11). The retainer is provided at its ends with guidin means along the ends of holder member adapted to overlie the adjacent ends of memher 8 with the retainer against member 7, for which purpose the end portions of the reprojections 14 adapted to be'enga tainer 12 are bent to enclose the corres nding end portions of member 7, providing s afced inwardly-disposed ears or lugs 12" on t e retainer that are adapted to overlie and engage said ends of member 8, spaces 13 being provided between member 12 and the ears or lugs 12' to receive the ends of members 7 and 8, (Fig. 8). By preference the end poi :ions 7" ofmember 7 are bent or formed laterally of such size as to substantially correspond to the thickness of blade 6 and holder member 8 when the parts 6, 7 and 8 are assembled, (Fig. 8), so that the ears or In s 12 will be gui ed by the parts 7" and wi overlie the adjacent projecting end portions 8 of member 8 to retain the latter clamped upon the blade when the retainer is a justed rearwardly or away from the blade edge, (Fig. 10). When the retainer is adjusted forwardly or in the direction of the blade edge sufliciently far the ears or lugs 12 pass beyond the free edge of holder member 8 to release the latter for application to the holder or removal therefrom of a blade 6, and 6). The member 7 is provide on its lower side with one or more projections 14 adapted to be engaged by the retainer 12 when the latter is moved forwardly or outwardly to release the holder member 8, Figs. 5 and 11), the retainer member being s own provided with recesses at 15 complemental to the projections 14 to receive the latter and accommodate the positions of the parts. The member 7 is also shown provided with projection 16 on its lower si e spaced frog: the

retainer 12 to resist the inward sliding o the latter when the same is being adjusted rearwardl y. The spaced stops 14 and 16 limit the sliding of the retainer in opposite directions along member 7. The retainer is shown provided with a recess 17 complemental to the projection 16 to accommodate the position of the arts.

e construction described is such that when a blade is to be inserted in the holder or removed therefrom retainer 12 is adjusted in a forward position so that its ears or lugs 12 will be disengaged from the member 8 so that the latter may be swung on its axis or shaft 9 to separate the holder members, (Fig. 12), whereb a blade may be laid upon member 7 withits notches 6 receiving the proections 11, (Fig. 12). MemberS next may be swung a ainst the blade, whereupon the retainer wi be adjusted rearwardly or toward shaft 9 so that its ears or In 12 will overlie the adjacent ends of mem r 8 and clam the blade between the holder members. The lade will be securely retained between the holder members so that the blade may be adjusted with respect to the guard or may be retained in the ho der for stroppin the blade edges. To remove a blade a simi ar adjust- (Figs. 5

merit of member 12 forwardly and back of member 8 is effected so that the b ade may be lifted from member 7.

In order to retain the blade in shaving position respecting the guard the retainer 12 is provided with forwardly disposed projections 18 ada ted to enter holding means shown in the orm of slots 19 located at opposite ends of the guard member, whereby the projections 18 ma engage the walls of said e slots to retain the lad ge relatively to the guard. The projections 18 and slots 19 are isposed in such relation that when the retainer, (while its In or cars 12 eng the holder member 8), is moved forward y toward the blade edge the projections 18 will enter the slots 19 and keep the holder with the blade in proper 'tion respecting the guard for shaving. win the blade is to be removed and replaced or stro ped the retainer is pushed back suflicient y far to release the projections 18 from t e slots 19 (Fi 4) to permit the release of the blade and its holder so that they ma be swung away from the guard, (Fig. 6) e projections 18 and slots 19 are disposed in such an angular relation respectin the guard that when the retainer is pushe toward the guard, from the position shown in Fig. 4), the sai projections on entering said slots will cause the blade to be drawn flatwise toward the guard. The more the projections 18 are entered in the slots 19 the more the blade edge will be forced toward the guard. If an ordinary shave is desired the projections 18 will be pushed substantiall fully down into the slots 19 to ress the blad e edge close to the guard, as in ig. 2, but if a closer shave is desired the projections 18 will not be ushed so far into the slots 19 so that the b ade edge will be raised slightly from the guard, as indicated in Fig. 7, there being suitable frictional enga ement between the retainer member 12 and the holder members 7 and 8 to retain said parts in set position.

This invention is illustrated in connection with a razor of the stropping variety, such as the well known Auto Strop safety razor. For such purpose the shaft 9 is provided with a gear 20 in mesh with a gear 21 that is secured to a roller 22 journaled in the uprights 2, 3 of the razor frame between shaft 9 and the base 1 for rocking the blade holder and the blade for stropping the latter. When a strop 23 is passed between roller 22 and the base 1 of frame 1, as indicated in Fig. 9, the razor may be reciprocated along the stro in a well known way, for rocking the blade holder and blade to and fro to alternately present opposite sides of the blade edge to the strop to be dragged along the same for stropping its edge.

This invention is simple and convenient in construction and mode of operation, afl'ording eflicient means for detachably securing a blade in its holder and for retaining the blade for shaving in any desired position of adjustment respecting the guard so that with a simple movement of the retainer the blade may be secured in desired shaving position.
